	\textbf{Some issues of general concern from the cognitive viewpoint}
	\begin{itemize}
		\item The fundamental properties of the environment
			
		\item The agent's relation to the environment
				
		\item The conditions and means by which the agent gets information about the environment
		\item How the agent's information is structured, represented, stored and accessed
		
		\item How the agent processes information
		\item How the agent makes use of its information to act successfully
